Biophotonics is the study of optical processes in biological systems, both those that occur naturally and in bioengineered materials. A particularly important aspect of this field is imaging and sensing cells and tissue. This includes injecting fluorescent markers into a biological system to track cell dynamics and drug delivery.
Enhanced light–molecule interactions in high-finesse fibre-based Fabry–Pérot microcavities are used to detect and profile individual unlabelled solution-phase biomolecules, leading to potential applications in the life and chemical sciences.
The stereoscopic photoacoustic microscopy is proposed to achieve wide-field intravital imaging of the lymphatic system in mice, facilitating three-dimensional high-resolution visualization of meningeal lymphatic vessels on the meninges.
Random-access wide-field mesoscopy enables the imaging of in vivo biodynamics in mice over an area of 160 mm2 and at a subcellular spatial resolution of about 2 μm.
A pioneer of DNA nanotechnology, Prof. Laura Na Liu from the University of Stuttgart in Germany, has been working at the interface, where nanophotonics meets biology and chemistry.
Trojan beams, which are optical counterparts of Trojan asteroids that maintain stable orbits alongside planets, have been successfully showcased in experiments, opening up possibilities for transporting light in unconventional settings.
